我有一个简单的Web应用程序来上传文件并将它们存储在longblob中的mysql数据库中。但我得到以下例外:
Caused by: java.sql.SQLException: Incorrect string value: '\xA2\x04\x02(\xA0\x00...' for column 'value' at row 1

这是我的表格:
<form id="myForm" action="/creategroup" enctype="multipart/form-data" method="POST">
<input type="file" name="component_1" id="component_1">
and other stuff...
这是该领域的Hibernate定义:
@Audited
@Column(name = "value")
@Lob
private byte[] value;
这是我对该字段的mysql定义:
value LONGBLOB NOT NULL
可能是什么问题?我该怎么检查?我应该改变什么来使它工作?
